ATOMIZER OR NEBULIZER.l

Specification of Letters Patent.

Patented March 20, 1906.

' To a/ZZ whom, it may concern:

Be it known that I, FRANK C. DORMENT, a citizen of the United States, residing at the city of, Kalamazoo, county of Kalamazoo, 5 State of Michigan, haveinvented certain new and useful Improvements in Atomizers orA` Nebulizers, of which the following is a specification. p

This invention relates to improvements in 1o atomizers ornebulizers.-

The objects of this invention are, first, to provide an improved atomizer or nebulizerin which the liquid medicament is retained in the flask no matter in what'position it may 15 be placed; second, to provide an improved atomizer or nebulizer which is simple and convenient to use; third, to provide an irnproved atomizer .or .nebulizer in which the parts are very simple and economical to prozo duce and are readily assembled; fourth, to provide. an improved atomizer or nebulizer which is readily disassembled for purposes of cleansing or the like and one which may be quickly reassembled by an inexperienced perz son.

5 vFurther objects and objects relating to structural details will definitely appear'from the detailed description to follow.v e

I accomplish the objects of my invention 3o bythe devices and means described in the e following specification.

,j The invention is clearly defined, and pointed out in the claims.

A structure embodying the features of my 3 5 invention is clearly illustrated inthe accompanying drawings, forming a part of this specification, in which- Figure 1 is a longitudinal sectional 'view thereof, a section of the air-supply tube be- Fig. 2 is a detail longitudinal sectional view'of a modified construction, the stopper-retaining cap A engaging the necks of the flask by friction instead of by screw-threads, as shown in Fig. Fig. Bis a detail longitudinal sectional view of the atomiZing-tube, showing a modifled constructionof check-valve for the airpassage of: the atomizing-tube.' Fig.v 4 is a longitudinal sectional view showing a modi-n 5o fied form of the atomizer-tubel- A In the drawings similar letters of reference refer to similar parts throughout ,the several views.r l

Referring tothe drawings, the' medicayment-flask A is open at each end and is provvided with outwardly-extending threaded necks. Tapered Stoppers a are provided. IThese Stoppers are retained in position by .threaded caps A which engage the outer 'tubeB is provided witha longitudinal airpassage b. The inner end of the tube B is chambered to receive the ball check-valve c for; the air-passage b. This` valve is held normally in its seat lby the coiled springe seat, it also closes the laterally-opening delivery-passage b of the air-passage b This l `7o one end of which bears against the ball c and Q the other against the cap B for the inner en d of the tube B. When the valve ois infitsdelivery-passage bl opens across the upper' end of the medicament-passage 6. The

medicament-passage b is preferably bored't I from the lower end, a hole 12 being bored through the flange b in line therewith, so that the medicament -passage is accessible for cleaning. With the parts arranged as I have illustrated and described the .air delivered through the air-passage b vlifts the valve c from its seat, thereby opening lthe air-delivery passage b. The delivery of the air under pressure across the upper end of the medicament-passage draws the medicament therethrough and delivers it against the wall of the ask, thereby atomizing the same.

The delivery-tube D is carried by the other stopper a. VThis tube is rovided/ with a flange d, corresponding to t e fiange b of the atomizer-tube B, for retaining the tube in position in the stopper. The inlet-ports for lthe delivery-tube Dvare formed longitudinally through the'laterally-projecting arms D. These arms are flaredl at their outer ends and serve as a trap to prevent the delivery of the liquid or medicament through the tube D. A suitablel the tube D.

IOS

Stoppers withdrawn. .The Stoppers-are pref-v erably made of cork, as they thus effectively hold the atomizing and delivery tubes in position and also effectively seal the fiask. The economy thereof is evident.

In the modified construction shown in Fig. 2 the screw-threads are omitted from the necks of the flask and the retaining-cap A is retained merely by friction. The valve c prevents the liquid medicament being drawn through the air-passage b', as sometimes occurs when the air buIb or pump works improperly. It also prevents any seepage of the liquid medicament therethrough when not in use.

In the modified construction of valve shown in Fi r. 3 a stem-valve c is provided. The form il ustrated in Fig. 1 is, however, preferred, as it not only effectively seals the air-passage b, but also the delivery-passage b therefor.

The particular style of medicament-trap for the delivery-tube D is very effective and economical to produce. Variations thereof will, however, appear to those skilled in the art.

In the modified construction of atomizertube shown in Fig. 4 the upper end of the tube B is' externally threaded to receive the threaded sleeve B. This sleeve is screwed down u on the tube B until it rests upon the iiange A perforation e is formed for the admission of the medicament. This tube or sleeve B" forms the medicament-passage of the atomizer-tube. A perforation is formed through the sleeve or tube B", adapted to be brought into registry with the air-delivery passage c. The cap Bm is in this structure threaded into the end of the outer tube or sleeve B. The valve c is arranged to close the air-passage and also the delivery-passage.

With the parts of my improved atomizer arranged as is illustrated and described they are very economical to produce and are quickly and easily disassembled for purposes of cleaning and the like and may be reassembled and adjusted Without any liability ofthe parts becoming disarranged. It is also very compact and convenient to use. The instrument with the medicament therein may be placed in any position without spilling the same, and it may, if desired, be set up ready for use in shipping and the medicament placed therein, if desired.

I A have illustrated and described my improved atomizer or nebulizer in the form preferred by me on account of its structural simplicity and economy, although I am aware that itis capable of considerable variation in structural details without departing from my invention.
